Of all the components in a modern vehicle, suspension bushes suffer some of the greatest stresses. Acting as the connecting interface between the vehicle's suspension arms and chassis, they are forced to withstand enormous amounts of force.

Traditionally, suspension bushes have always been made from rubber. Unfortunately, although rubber has undergone a great deal of development over the years, it's still prone to deterioration due to oxidisation and chemical reaction, becoming softer and less able to offer resistance to the huge forces placed on it. When rubber suspension bushes deteriorate, they cause the suspension to have incorrect geometry, which in turn causes increased tyre wear, instability under braking, and poor handling.

Vast improvements have been made in the field of suspension by the use of polyurethane bushings instead of rubber. Polyurethane is a chemically inert compound which is not prone to the same problem of oxidisation which rubber suffers. Recent advances in the development of polyurethane mean that suspension bushes made from this synthetic material offer the same ride quality as the older rubber bushes, but with a significantly increased lifespan. Polyurethane has the elasticity needed to absorb the shocks and vibration from the suspension, whilst also having high tensile strength which provides durability under the toughest conditions.
